The PCM is an advanced version of the ECU that controls not only the engine but also the transmission system. It coordinates the functions of the engine and transmission to ensure seamless operation and efficient power delivery. How do ECUs, PCMs, and ECMs Work? These control modules receive input from various sensors throughout the vehicle, such as the throttle position sensor, oxygen sensor, and mass air flow sensor. They use this information to make real-time adjustments to fuel injectio...
